Subject: [GIT PULL] Xen APIC hooks (with io_apic_ops)

Hi Ingo,

Here's a revised set of the Xen APIC changes which adds io_apic_ops
to allow Xen to intercept IO APIC access operations.

Thanks,
	J

The following changes since commit ce791368bb4a53d05e78e1588bac0aacde8db84c:
  Jeremy Fitzhardinge (1):
        xen/i386: make sure initial VGA/ISA mappings are not overridden

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git for-ingo/xen/dom0/apic-ops

Gerd Hoffmann (2):
      xen: set pirq name to something useful.
      xen: fix legacy irq setup, make ioapic-less machines work.

Ian Campbell (1):
      xen: pre-initialize legacy irqs early

Jeremy Fitzhardinge (14):
      xen/dom0: handle acpi lapic parsing in Xen dom0
      x86: add io_apic_ops to allow interception
      xen: implement io_apic_ops
      xen: create dummy ioapic mapping
      xen: implement pirq type event channels
      x86/io_apic: add get_nr_irqs_gsi()
      xen/apic: identity map gsi->irqs
      xen: direct irq registration to pirq event channels
      xen: bind pirq to vector and event channel
      xen: don't setup acpi interrupt unless there is one
      xen: use acpi_get_override_irq() to get triggering for legacy irqs
      xen: initialize irq 0 too
      xen: dynamically allocate irq & event structures
      xen: disable MSI
